CPT code 33840 represents open surgical excision of an aortic stricture with primary anastomosis, often used to treat focal aortic narrowing such as coarctation and may include concurrent repair of a patent ductus arteriosus. This procedure is significant nationally because it addresses critical congenital or acquired aortic obstructions that can have major hemodynamic consequences and typically requires inpatient surgical resources and specialized cardiovascular surgical teams.

Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context about the procedure, typical site-of-service expectations, and a national framing of why accurate coding matters for clinical reporting and hospital billing workflows. The publication also covers common modifier usage and payer coverage patterns where available, benchmarks for utilization and reimbursement when present, and relevant policy considerations that affect surgical cardiovascular coding. Data not available in the input are identified explicitly in the appropriate sections. The content serves as a concise reference for clinicians, coding professionals, and policy analysts seeking to understand the coding and high-level implications of CPT code 33840.
